I was looking at the big static model shark that I built a few years ago, and I was wondering whether it would be possibly to build a similar-sized model from balsa/ply, BUT instead of plank-on-frame, I was thinking planks of balsa butt-joined together (with another piece of wood glued into the corners for strength), then sanded to shape, liberally covered in perhaps varnish or fibreglass resin, and finally painted.

What do you guys think?

(Remember, it's just an idea! )
